Still, we treat our soil like dirt. By growing food and storing carbon dioxide and water, the loam and peat that coats the earth sustains us all. In return, we till it, treat it with chemicals and generally walk all over it.

Without healthy soil, food becomes less nutritious and crops become harder to grow. If the crops aren’t healthy, then the 70 percent of the world’s fresh water that’s used for agriculture will be wasted.
